Part Number: BQ21080 Tool/software: Dear TI Engineer,
In our smart galsses project, we found that when increasing the load (enable the WiFi function) will cause VSYS to lose power. The application diagram is as follows:
We measured the waveform when…

Hello
I am using BQ21080 in my project. I want to charge my 18650 Li-Po Battery with CC-CV. I set the regulation voltage to 4200 mV and the charge current to 800 mA,
I started the charge cycles. The first constant…

Here is SHENZHEN MM FAE Chris, my customer has some questions as follow:
The customer wants to have some modifications based on BQ21080.
1. Use it only as a power…
Hello Hemry,
I received the mouse PCBA and was able to recreate the issue in our lab. I've also reached out to your FAE to start the failure analysis (FA) process. Given that this issue went away with an ABA swap, it seems possible that the root cause…
Part Number: BQ21080 Tool/software: Hello,
If the power is removed (neither VIN nor VBAT), will the BQ21080 store the user configurations? Or will it revert to the default settings?
Also, which are the default settings?
Thank you.
Best regards,
João…
Part Number: BQ21080 Tool/software: We are in need of information on the UBM (Under Ball Metallization)/SRO (Solder Resist Opening) of this device BQ21080YBGR
We need this for our DFM team to define their own land pattern.
Thank you,

Part Number: BQ21080 Tool/software: Dear TI Engineer,
We are wondering what is the minimum voltage threshold for the TS/MR pin of BQ21080 in response to long pressing the external power button to exit ship mode. That is, what the voltage of TS/MR pin…
Hi Dushyantha,
The BQ21080 is defined for a smaller footprint, so minimizing the number of external pins was a priority in that part. Most of the configurability of the BQ21080 comes via I2C, this is how device modes such as shipmode and shutdown mode…
